A 9:16 crop workflow that keeps browser reel assembly honest

It does not generate a video from a prompt, auto-pick highlights, add captions or music, or promise reach.

Editing and preview are free. Finished MP4 export is on the Starter plan at $19.99/month. That boundary is intentional: use the free tools to validate the framing and sequence before deciding whether the export workflow fits.

The general lesson: make the crop decision visible, keep the subject in the safe area, and let the editor handle the mechanical assembly—not the creative judgment.
